Background: In order to reverse the
White -lipped
peccary decline, besides protecting its
habitat and controlling
hunting ,it is necessary a captive
breeding program. There are
reports , however, on the low
fertility of
white -lipped
peccary , makingit difficult its
reproduction in captivity, making
artificial insemination one of the main tools to prevent the loss of geneticdiversity of species kept in captivity. Information on safe
methods of
anesthesia and the collection of
semen should beinvestigated. Therefore, we aimed to compare the effects of the
anesthetic protocols acepromazine /
ketamine and
xylazine /
ketamine , as well as electroejaculation
protocols , for
semen collection in
white -lipped
peccary (Tayassu pecari).Materials,
Methods &
Results: Twelve
adult male white -lipped
peccaries were submitted both to the
xylazine /ketamineand
acepromazine /
ketamine anesthetic protocols . The
anesthetic induction
time and duration, the degree of
muscle relaxation , the
time for
anesthetic recovery and the quality of the
animals recovery were evaluated. Additionally, the qualityof the sedation was evaluated based on the
animal s
behavior . We also evaluated the effect of
drugs on erectile functionsas well as the
efficiency of 3 electroejaculation
protocols with increasing or fixed voltages (2 to 4 V; 5 to 12 V; 12 V). Theacepromazine/
ketamine combination promotes shorter induction
time , duration and recovery from
anesthesia than thexylazine/
ketamine association . There were no differences, however, between the tested
anesthetic protocols in relation toheart
rate, respiratory rate and
temperature . Ejaculate was obtained from only 2
animals when using the
xylazine /ketamineprotocol and
adoption of stimuli between 5 and 12 V, with 10 stimuli at each voltage. In turn, ejaculate was obtained from4
animals submitted to the
acepromazine /
ketamine protocol, 3 of them with the
adoption of stimuli between 5 and 12 V...
